Surah Al-A'raf — Ayah 9 (7:9)
وَمَنۡ خَفَّتۡ مَوَٰزِينُهُۥ فَأُوْلَٰٓئِكَ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُم بِمَا كَانُواْ بِـَٔايَٰتِنَا يَظۡلِمُونَ ٩
English translation (Saheeh International)
And those whose scales are light - they are the ones who will lose themselves for what injustice they were doing toward Our verses.
Brief commentary
Those whose bad actions weigh more than their good actions are the people who have lost themselves, gaining their destruction on the Day of Judgement and being excluded from eternal bliss because of their rejection of Allah’s signs and verses.
